Another object of this invention is to provide a compact and durable floodlight assembly of the character described, which shall be relatively inexpensive to manufacture, readily assembled and wired, and which shall yet be attractive in appearance, easy to use, practical and efficient to a high degree.

Other objects of this invention will in part be' obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combination of elements,

and arrangement of parts which will be exemplified in the construction hereinafter described,

Fig. 3 'is a cross-sectional view taken on the line3--3 of Fig. 2, and showing a socket mounted in the assembly;

Fig. 4 is across-sectional view taken on the line 4--4'of Fig. 1; and

Fig. 5 is an elevational view of a pair of floodlight assemblies embodying the invention, mounted on the cross arm of a support.

Referring now in detail to the drawing, designates a floodlight assembly embodying the invention. The same comprises a housing generally designated as H, and a combined conduit and support pivotally connected to said housing, generally designated as 12.

The housing ll comprises a generally tubular walled member I3 having the major portion thereof cylindrical and closed at its rear end by a wall 14. Extending from the forward end 01' member I3, is a flared, part spherical walled portion l5. Extending longitudinally from the lower portion of tubular wall 13 is an enclosed passageway I6 in defining a channel having its open side directly in communicating with the interior of said tubular member. The passageway or channel [6 is formed by a pair of parallel, vertical walls ll, i8 interconnected by a bottom wall I52, and a back wall 2-fl,'whichis an extension of wall M.

It will be noted from a consideration of Fig. 4, that the passageway I6 is off centre with respect to the longitudinal axis of tubular member l3, the outersurface of wall I! defining a plane substantially coinciding with a vertical central plane longitudinally through said tubular member. The front wall 2| of passageway or channel 1-8 is spaced inwardly" of the front end of tubular member l3, as shown in Fig. 3.

Extending downwardly from a forward portion of walls l1, H3, is a vertically disposed enlarged, dome shaped walled bracket 22. The bracket 22 communicates at its upper end with the passageway or channel 15. The bracket 22 comprises a base with an annular vertically disposed edge 23, which is in the plane of the outer face of walllll. a centrally dispcsedthickened wall portion 24 through which extends a horizontally disposed opening 24a, for the purpose hereinafter appea-ring.

on the inner side ofits rim with a peripheral The bracket 22 furthermore comprises.

recess 25 which receives a soft resilient annular gasket 26, suitably retained therein by adhesive or the like.

, Extending forwardly from the inner surface is an enlarged, dome-shaped walled bracket 32,

bracket 22.

which is complementary in shape and size to the bracket 22 on housing i i. The base of bracket 32 comprises a vertically disposed annular edge portion 33 disposed opposite edge portion 23 on Extending from edge portion 33 is an annular lip 34 which projects into the annular opening formed by the edge of bracket 22. An annular resilient gasket such as rub ber or the like, is mounted on the lip 3d, 'The bracket 32 isgformed with a centrally disposed thickened wall portion 35 through which extends a horizontally disposed Opening 36a which is aligned with the opening 24a in bracket 22. A set screw or bolt 31 passing through the aligned openings and a nut 38 thereon, secure the brackets 22, 32 together, thereby forming an enclosed chamber therebetween. A look washer 39 is. on the screw or bolt 31, being disposed between the head thereof and the thickened wall portion 24. The housing H is thus adapted to be rotated or tilted with respect to the support I2 through the interfitting edges of the brackets 22, 32.

It is apparent that thereis through communication between the interior of tubular member l3, through passageway [6, the chamber formed by brackets 22, 32, the offset tubular portion 3| and nipple 30.

A conventional fioodlight socket 40 is coaxially mounted within tubular member l3, the rear portion thereof abutting the projections 21, 28. The socket substantially fills the rear portion of the housing and is secured in spaced relation to back wall M by headed screws 4|, passing through the socket. and received in threaded openings 29 in wall l4. Wiring 42, connected to the usual screw contacts on the rear of socket 411, runs parallel to the socket, being disposed in passageway 15 and extends through the chamber formed by brackets 22, 32, around screw or bolt 3'! and continue downwardly through oiTset tubular portion 3| and nipple 30, as indicated'in Fig. 3.

The nipple. 30 is provided with a lock nut 43 whereby the supporting portion l2 of the floodlight assembly, may be suitably secured to a thereby protectingit from the weather, .The

gasket 35 insures a close fit between-the joint portions of brackets 22, 32, further rendering the jointweather proof. Y

" The gasket 26 on the rim of the flared portion l5 of housing II which may be made of fibre,

rubber, or the like, is adapted to seat exterior portions of a floodlight bulb, not shown, which is screwed into or otherwise mounted in socket 40. In this manner, the inserted lamp effectively seals off the interior of the housing against the ingress of water or the like. Furthermore,

the compressibility of gasket 26 provides for the post 5|. The threaded nipple 30 of the support l2 may be suitably received in threaded openings in the upper surface of the cross arm 50 and the nuts 43 may be used to lock the support to the cross arm. It is apparent that the wiring 42 from each of the assemblies I!) may be extended from the nipple 30 into the hollow arm 50 and down through the post 5| to bewappropriately con nected to suitable power lines. Each of the assemblies may be tilted to a desired position and locked-in such position, as previously described.

The housing I I and support l2 may be made of cast metals or other materials which are weather proof and adapted to use for the purpose described.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved and which is well adapted to meet the, conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth. it is to be understood that all matter here.- in set forth or shown in the accompanying drawings is illustrative and not in a limiting sense, except as set forth in the claims.
